Registration of PR0633-10 and PR0737-1 Red Mottled Dry Bean Germplasm Lines with Resistance to BGYMV, BCMV, BCMNV, and Common Bacterial Blight

Bean golden yellow mosaic virus (BGYMV), Bean common mosaic virus (BCMV) and Bean common mosaic necrosis virus (BCMNV) are important diseases of dry bean (Phaseolus vulgaris L.) in Central America and the Caribbean. The development of dry bean cultivars with enhanced levels of resistance to these and other diseases is an important goal of the University of Puerto Rico (UPR) and other dry bean breeding programs in the Caribbean. PR0633-10 (Reg. No. GP-290, PI 668535) and PR0737-1 (Reg. No. GP-291, PI 668536) are multiple virus resistant bean germplasm lines adapted to the humid tropics that were developed and released cooperatively in 2013 by the UPR Agricultural Experiment Station, the USDA-ARS, the Instituto Dominicano de Investigaciones Agropecuarias y Forestales, and the Ministry of Agriculture, Natural Resources and Rural Development of the Republic of Haiti. Both lines have a red mottled seed type. PR0633-10 possesses the I and bc-3 loci that confer durable resistance to BCMV and BCMNV, whereas PR0737-1 only has the bc-3 locus that confers resistance to BCMV and BCMNV. Both lines have the bgm-1 gene for resistance to BGYMV, whereas PR0633-10 also has the SW12 quantitative trait locus associated with resistance to this virus. PR0633-10 and PR0737-1 produced mean seed yields as great or greater than check cultivars 'PC-50' and 'JB-178' in trials conducted in Puerto Rico, the Dominican Republic, and Haiti. Both lines should serve as useful sources of resistance to BGYMV, BCMV, and BCMNV.
